Except that capitalist competition is precisely what leads to centralization and concentration of capital. The way competition works is that winners grow making it harder for new players to enter the market. You need more up front capital to even try while the existing players get to leverage economies of scale, and if a new company becomes a threat they can just buy it out or run it out of business. That's precisely how current tech monopolies were born with smaller companies like WhatsApp, YouTube, Instagram, and so on, all being absorbed by a handful of giants. You're just regurgitating slogans here without any actual understanding of the subject.
